PASTEURIZER.

Specification of Letters Patent.

Patented June 6, 1911.

Application filed October 19, 1908. Serial No. 458,543.

To all whom it may concern:

Be it known that I, BRYAN D. PINKNEY, a citizen'of the United States,and a resident of Cleveland, county of Cuyahoga, and State of Ohio, haveinvented anew and useful Improvement in Pasteurizers, of which thefollowing is a specification, the principle of the invention beingherein explained and the best mode in which I have contemplated applyingthat principle, so as to distinguish it from other inventions.

The present invention relates to improvementsin pasteurizers asindicated; its more particular relation, however, is to pasteurizers ofthe continuous type, such as are used in beer-bottling establishmentsand the The object of the invention is the provisiofi. of continuouspasteurizing apparatus whereby increased thoroughness and economy ofpasteurization is accomplished, while at the same time, by. suitablebalance and symmetrical disposition of moving parts, operative lossesare reduced to a minimum.

To the accomplishment of the above and.

related ends, said invention, then, consists of the means hereinafterfully described, and particularly pointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in which thei principle of the invention may be used;

In said annexed drawings: Figure 1 is a diagrammatlc sectional view ofmy improved pasteurizer as adapted for use either in a one storiedbottling house with the tank in a pit, or in a two storied bottlinghouse with the tank in the basement; Fig. 2, is a side elevation of suchpasteurizer; Fig. 3, is a view similar to Fig.- 1, but illustrating theadaptation of the apparatus for use in a two story bottling house withthe tank on the second floor; Fig. 4, is a side levational.

view of one of the thermostatic control-devices employed in connectionwith mypasteurizer; andllig. 5 is an end elevatlonal view 'of'the same.v

The main feature of the apparatus in each of'its several modified formsof construction, is a tank A suitably supported either in a pit orbasement or on a floor of the bottling house, as occasion may demand.Such tank is of rectangular form, and is separated into four alinedvertical chambers, A A A A, by transverse partitions, a a a rising froma horizontal partition, a, whereby the horizontal chamber or passage Ais provided beneath the two innermost, A A of said alined chambers whichhorizontal chamber, as will be obvious, serves to connect the lowerportion of the two remaining or outermost chambers, A? A. chambers arefurther separated by parti- Said two innermost tions, a a depending fromabove into two compartments, a a a a", respectively;

. conveyer b is guided through the chambers in such fashion as tosuitably carry the trays or other carriers 12 in which the bottles orlike articles to be pasteurized are placed.

Outside of the pasteurizing tank A, such endless conveyer may obviouslybe conducted as suits the convenience of each individual installation,either terminating just above the open tops of the compartments as shownin Fig. 1, or else being carried over I other sheaves B without thepasteurizer to any desired point or points in 1fhe plant,

ing point perhaps three or four degrees R. It accordingly becomesnecessary to preliminarily heat or attemperate the beer beforesubjecting it to the pasteurizing temperature. So too, incidentally toremoving the beer from the pasteurizing chamber, its temperature shouldbe gradually lowered, so that upon removal from the apparatus, it willbe restored to the normal temperature at which it is maintained forpurposes of storage or shipment, all without being subjected at any.

time to the shock of a sudden change in temperature. The arrangement ofchambers and compartments Within the tank of my improved pasteurizer,has hence been designed with a view to facilitate the'maintenance of theproper temperature of the-body of water contained within said tank orchamber, to which end the following additional means are provided. Onthe exterior of the tank, and laterally of the same there are providedat each end two pipes or conduits, C, the lower ends of which areconnected with the horizontal chamber or space.

A at points a near its center, the upper ends of which branch and openinto 'the upper portion of the respective outermost vertlcal chambers,either A or A. By means of a steam injector C of familiar construction,and hence not requiring detailed description in this connection, acirculation of water may be maintained from such lower point 0.

of connection of each pipe C to thepoints c 0 where its branched upperend is connected with the outer pasteurizing chambers, thence downwardlythrough each outermost chamber to the lower end of the pipe again. Aswill be readily understood, such injector serves at the same time tomaintain the water, thus put in circulation, at the proper pasteurizingtemperature, and that such temperature may be automatically maintainedwhen the apparatus is in operation, thermostats C likewise of' fa miliarconstruction, are employed in conjunction with each of the circulatingpipes, C. These thermostats are mounted laterally of the correspondingtank portion near the upper end of the circulating pipe, and are adaptedby means of suitable pressure-air connections 0 and a diaphragm valve 0to appropriately operate the corresponding injector, whenever thetemperature at the point of attachment of the thermostat to the tankfalls below, or rises above the pre-determined temperature.

While by the means just described, the body of the water throughout'theconnected series of chambers A A A, will be uniformly heated to thepasteurizing temperature and so maintained the water in chamber A willtend to lose, and that in chamber A i to gain heat, since the coldbottles are assed through the former and the heated bo'tt estare passedthrough the latter. For the purpose, hence, of overcoming these effectsand more or less equalizing the temperatures in the two chambers justnamed, I provide a cold spray above the water line in compartment awhereby the tendency of the body of water 7 in such compartment tobecome unduly heated is overcome; the spray, falling as it does directlyon the bottles as they emerge, serves to finally cool the latter. Inthe'case of the other compartment a, I have found that by reason of theparticular arrange- .ment of partitions, the water therein will beproperly attemperated by conduction from the space A through thecompartment a.

From the foregoing description of the:

construction of my lmproved pasteurizing apparatus, it will be seen, ashas already been remarked, that by reason of thesymmetrical dispositionof the chambers, and

consequently of the corresponding portions 7 of the conveyer' passingtherethrou -h, an even pull is at all times secured, so ar as mechanicaloperation of the apparatus is concerned; Moreover, the feed anddischarge points of the apparatus are brought closely together, thuspermitting the remain der of the more or less cumbersome tank to bedisposed out of the way, a feature frequently permitting considerablesaving of room.

All this is obtained without sacrificing the extent of the passage, orseries of connected chambers, wherein the actual pasteurization isefiected. At the same time in maintain-- tance, for the crates or traysare of a consid-- erable length (such that in fact the tank of thepasteurizer requires to be six or more feet in width), as result ofwhich one side of the pasteurizer may be at the proper temperature, andthe other side too cold. This has particularly been apt heretoforeto bethe case where partially filled trays are put through the pasteurizer,but no such difliculty can arise with the present arrangement.

Other modes of applying the principle of my invention may be employedinstead ..f the one explained, change being made as regards themechanism herein disclosed, provided the means stated by any of thefollowing claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my inventionl.
